History FanFic / HalloweenWorld

* BrotherChuck: The absence of Spike, Drusilla, or, most jarringly, Angel is never pointed out by any of the characters. Subverted in that they do get their own side story instead of just disappearing.

* FireForgedFriends: See EnemyMine.
* TheFourGods: [[Manga/InuYasha Naraku's]] QuirkyMinibossSquad

* GeniusLoci: Citadel City.

* LoadsAndLoadsOfCharacters: The pre-timeskip arc introduced a handful of characters every chapter, until the cast was well over a hundred by the end of it. The post-timeskip arc introduces so many characters per chapter that it can be a little difficult to keep up.

In the world of Series/BuffyTheVampireSlayer CrossOver fanfic, no plot is used quite as much as the YAHF (Yet Another Halloween Fic) story. Halloween World takes this somewhat over used idea to its absolute extreme with a few unexpected twists.

!!Tropes particular to the story itself include:

* BoringInvincibleHero: The good guys never lose and only a couple of them have died. On the other hand, the war does go on for almost twenty years and the 'offscreen' death toll is pretty high, not to mention that while the important characters survive the unnamed ones get slaughtered.

<<|FanFic/FanFics|>>

* BadAss: About 90% of the population. Non-badasses tend not to live very long.

* AfterTheEnd
* AlternateCharacterInterpretation - there are a number of characters who are living examples of this trope in action. As the author put it, perception is the basis of reality, so different versions of the same character differ according to the character interpretation of the person who wore the costume on halloween.
* AlternateUniverse-The story itself, obviously. There are also several characters who are alternate universe versions of each other.
* ApocalypseNot- [[JustifiedTrope Justified]] since given the amount of firepower, magic and SciFi level technology that's around after the Event humanity and equivalents were more then able to survive, adapt and develop.
* AuthorAvatar-One does appear once, but he has very little relevance to the plot. There’s also an avatar of a frequent reviewer who makes a few appearances.
* BadAss- About 90% of the population. Non-badasses tend not to live very long.

** ''“We don't fear death. We don't fear life. We adapt and we survive. We are the warriors of Hallow Earth!"''
** '' "Killing is acceptable, murder is a sin"'' and variations thereof.
* BadAssFamily- There are numerous examples, one of the most (in)famous and terrifying being what you get when you combine three versions of a certain bell wearing BloodKnight of a shinigami, a number of women who are as crazy as he is and an out of control lust/fertility spell to kick start things. Four words: second generation [[BloodKnight Blood Knights]].
* BlessedWithSuck- There are a few notable examples. For instance, there's a guy who went as [[Manga/{{Inuyasha}} Naraku]] and got through Halloween with his personality intact. Unfortunately, his mum went as Kikyo and wasn't as lucky. Gaining the abilities of a powerful bad guy while keeping your own personality may sound like a good deal, but when your own mum tries to kill you due to mistaking you for said bad guy it's a different matter altogether.
* BoringInvincibleHero-The good guys never lose and only a couple of them have died. On the other hand, the war does go on for almost twenty years and the 'offscreen' death toll is pretty high, not to mention that while the important characters survive the unnamed ones get slaughtered.
* BrotherChuck-The absence of Spike, Drusilla, or, most jarringly, Angel is never pointed out by any of the characters. Subverted in that they do get their own side story instead of just disappearing.
* CursedWithAwesome-Even curses that were detrimental in a given characters universe can become extremely useful in Halloween World.
* DarkIsNotEvil- For one reason or another most of the world's population are dark to some degree so this particular trope is a fact of life.
* DemotedToExtra-All of the [[Series/BuffyTheVampireSlayer BtVS]] cast except Xander post-timeskip. They do occasionally get their moments in the spotlight, but it tends to be fairly short lived.
* DepopulationBomb- It's stated outright that billions of people died after the Halloween Event.
* DeathIsCheap- {{Lampshaded}} to hell and back. One of the side stories even has the trope name as a title.
* EnemyMine - finding yourself in a world of monsters has a way of changing your priorities and a lot of former enemies find themselves working together in order to survive and/or fight the {{BigBad}}s.
* ExtranormalInstitute-Several are mentioned throughout the series.
* FaceFault- Thanks to the large number of anime characters, the physics of the 'verse have been altered to make face faults extremely common.
* FireForgedFriends -See EnemyMine.
* TheFourGods-[[Manga/InuYasha Naraku's]] QuirkyMinibossSquad
* FourIsDeath-Several examples, but the four final {{BigBad}}s are probably the best example.
* GeniusLoci- Citadel City.
* HalfHumanHybrid-Very common. Examples in the main story include human/demon, human/youkai, human/alien and human/[[Manga/{{Bleach}} shinigami]]. One of the side-stories has human/passling and human/bear (both cases involved a very over powered and out of control lust/fertility spell) while another has a reference to human/[[Manga/{{Bleach}} Arrancar]]. That's without even going into all of the half anything but human hybrids.
* HeinzHybrid- Take a world populated by pretty much every fictional species ever thought of, add one or two out of control love spells plus a few other motivating factors and, as one reviewer put it, it's safe to say that what passes for humanity in the Hallow-verse is well on its way to an advanced state of muttiness.
* HeelFaceTurn- Numerous examples, one of the most blatant being the fact that the forces fighting on the good side in the final battle against Aizen included former Espada. As one of them put it “Following him didn’t turn out well in our last life."
* HorsemenOfTheApocalypse-[[{{Manga/Berserk}} Griffith's]] QuirkyMinibossSquad.
* HotSkittyOnWailordAction-Happens with a number of species, but Pokémon/[[{{Obake}} Yokai]] hybrids are mentioned several times.
* InferredHolocaust- After a fashion. There are plenty of survivors and they seem to be doing well, but between a quick and dirty form of natural selection (it's nigh impossible for a normal human to survive without protection from a colony or someone with superpowers) and the knock-on effects of the chaos magic, humanity as we know it is pretty much scuppered.
* InfoDump-A lot, usually from the narrator.
* InterspeciesRomance - See HeinzHybrid example.
* LastStand- Humanity, plus equivalents and allies, ends up fighting a world war against a mixed bag of {{Big Bad}}s for almost two decades.
* LoadsAndLoadsOfCharacters- The pre-timeskip arc introduced a handful of characters every chapter, until the cast was well over a hundred by the end of it. The post-timeskip arc introduces so many characters per chapter that it can be a little difficult to keep up.
* MegaCrossover- Mostly anime.
* {{Magitek}}- There's a heck of a lot of it, used for pretty much everything.
* TheNightThatNeverEnds
* OneWingedAngel-Used several times and lampshaded at least once.
* OriginalCharacter-Most of the character come from some canon, but there are several notable original characters. Due to the nature of the Halloween Event there are also numerous examples of the latter in the bodies of the former.
* {{Psychopomp}}- Every conceivable version thereof. On of the side stories even featured them having a meeting to sort out how they were going to work together. Interestingly, the living can see them, know what they are, and following the timeskip at least don't seem to be particuarly bothered that Death is literally walking the streets.
* QuirkyMinibossSquad-Each of the final Big Bads have one.
* RedSkyTakeWarning- The Red Sky, a part-electromagnetic, part-magical barrier that doesn't allow anything to go through it, fries almost all forms of aircraft and periodically unleashes various kinds of hell on the world below.
* RuinsOfTheModernAge- The story includes frequent mentions of ruined cities, most notably Los Angeles.
* SerialEscalation- It's safe to say that the latest plot arc qualifies.
* SpotlightStealingSquad- Xander gets far more attention than any other [=BtVS=] character.
* SleptThroughTheApocalypse- One of the spin off stories involves a man who went into magically induced suspended animation in a desperate attempt to survive terminal cancer. He spent seventeen years in a locked trunk before being discovered by chance and revived. FishOutOfTemporalWater, ValuesDissonance and PostHistoricalTrauma ensues.
* TimeSkip- The first arc is set in the months after the Event; the second kicks off 12 years later.
* TranslatorMicrobes- Done in a rather original way, namely a 'viral language' that spreads faster than the common cold.
* TranslationConvention- It is heavily implied that post-timeskip people's original languages has been largely replaced by the above mentioned viral language. To the reader of course, everyone's speaking English.
* {{Troperiffic}}
* UnwantedHarem-Xander's wives, though the unwanted part is dropped post-timeskip.

* BlessedWithSuck- There are a few notable examples. For instance, there's a guy who went as [[{{Inuyasha}} Naraku]] and got through Halloween with his personality intact. Unfortunately, his mum went as Kikyo and wasn't as lucky. Gaining the abilities of a powerful bad guy while keeping your own personality may sound like a good deal, but when your own mum tries to kill you due to mistaking you for said bad guy it's a different matter altogether.

* TheFourGods-[[InuYasha Naraku's]] QuirkyMinibossSquad

* HorsemenOfTheApocalypse-[[{{Berserk}} Griffith's]] QuirkyMinibossSquad.

* TheEternalChurchill- Humanity, plus equivalents and allies, ends up fighting a world war against a mixed bag of {{Big Bad}}s for almost two decades.
